BACKGROUND

This invention relates to a medical system assisting more efficient and safer performance of otorhinologic medical procedures. More particularly, this invention concerns a medical system comprising apparatus and methods for improved ear-canal and nasal-passage irrigation.

With respect to ear canal irrigation problems, when a patient complains of a foreign body or cerumen impaction within the external ear canal, it is desirable to irrigate the external ear canal with a solution such as normal saline. Presumably the dilution effect of the irrigation will wash out cerumen and debris. A physician or user may wish to control the source and positioning of an irrigation stream. For example, improper positioning of an ear canal irrigation device may sometimes present the risk of trauma, e.g., to the external ear canal. A need exists for a device that will assist the physician or user with the proper positioning of an ear canal irrigation device.

With respect to nasal-passage irrigation problems, the procedure generally requires the patient's head to be located over a sink or similar catch basin. This is not always convenient for the patient or caregiver.

When using large volumes of liquid or high amounts of pressure, contaminated liquid may spread to unwanted surfaces, including splashing onto a health care provider or drenching the patient. This is undesirable as, e.g., the risk of spreading of disease is heightened and there may be undesirable effects of getting a patient wet. The excess liquid may also soil laundry and require increased housekeeping services, using existing methods of irrigation. The excess liquid may also be an inconvenience for otherwise healthy patients; they may have to remove their clothing to prevent them from getting soaked. The above situation may be uncomfortable for the patient in a busy emergency room; and, the time necessary for the patient to disrobe would delay a doctor's or nurse's ability to treat such patient or other waiting patients more expeditiously. These disadvantages may decrease the incentive for an operator, such as a physician, to appropriately use optimal large volumes of irrigation liquid, and therefore the difficulty of properly irrigating the ear canal increases.

A female threaded device does not exist that fit any of the commercially available standard wide-mouth irrigation pour bottles. There exists a need for a nasal irrigation device that fits these common sources of reliable sterile fluid to avoid having to stock additional nasal irrigation bottle fluid containers that can only be used for nasal irrigation. Furthermore, since at a single clinical location these standard wide mouth irrigation bottles may come from different suppliers at different times based on various market factors, there is a need for a device that is compatible with all three types of commercially-available standard wide-mouth irrigation pour bottles, so a nurse or physician does not lose valuable time, for example, in a busy emergency room, searching for a female threaded irrigation device compatible with each type of irrigation bottle, and so the supply chain purchasers do not have to order a different adapter for each commercial manufacturer of standard wide mouth irrigation bottles.

Furthermore, there exists a need for better irrigation devices using commonly available plunger syringes for flushing the nasal passages of children and adults using common sources of medical grade irrigation fluid such as standard wide mouth irrigation pour bottles and prefilled saline syringes.

OBJECTS AND FEATURES OF THE INVENTION

A primary object and feature of the present invention is to provide a system overcoming the above-mentioned problem(s).

It is a further object and feature of the present invention to provide an otorhinologic irrigation system for collecting liquid draining from an ear canal or nasal passage. It is another object and feature of the present invention to provide an otorhinologic irrigation system capable of assisting to prevent irrigation liquid from splashing onto a health care provider or drenching the patient.

It is a further object and feature of the present invention to provide an otorhinologic irrigation system capable of assisting with the proper positioning of an irrigation device within the ear canal. It is a further object and feature of the present invention to provide an otorhinologic irrigation system capable of easily accommodating connection with a variety of different sources of irrigation liquid. It is another object and feature of the present invention to provide a multi-purpose otorhinologic irrigation system comprising adapters capable adapting a multi-purpose otorhinologic irrigation device to a particular otorhinologic structure.

Nozzle portion 213 preferably functions to facilitate the injection of irrigation liquid 117 into one or more otorhinologic structures of the patient's head (at least embodying herein at least one liquid injector structured and arranged to assist injection of the liquid into an otorhinologic structure of the head). In the present preferred embodiment, the nozzle preferably functions to administer a sterile liquid saline solution into the patient's nasal passages and sinus cavity.

Nozzle portion 213 is preferably configured to form a seal with the patient's nostril 209 during treatment (see FIG. 11). Thus, nasal bulb 214 preferably functions as an anatomical adapter to adapt the liquid-injecting structures of the apparatus to the anatomical geometries of the target otorhinologic structures of the patient's head.

Nasal irrigator 203 is preferably configured such that irrigation liquid 117 exits the distal end of nozzle portion 213 through a discharge port 210, as shown. As will be discussed in greater detail below, discharge port 210 is in fluid communication with the manually-deformable internal reservoir of irrigation squeeze bottle 102.

Preferably, the upwardly-sweeping periphery of surrounding wall 218 accommodates the anatomical structures of the head while generating an elevated splash shield 227 to assist in preventing splashing of liquid-containing effluent 118 beyond the effluent collector.

Referring to the sectional views of FIG. 14 and FIG. 15, nasal irrigator 203 preferably comprises coupler 220 to enable the removable coupling of the apparatus to the irrigation squeeze bottle 102 shown in FIG. 11. In a preferred arrangement, coupler 220 comprises a threaded an internally-threaded coupler 220 configured to threadably engage the external helical threads 122 formed within the cylindrical neck 103 of irrigation squeeze bottle 102. As in the prior-described embodiments, a preferred coupler configuration comprises a cylindrical member 225 having an inner bore 231 containing a set of helical threads 223, as shown. The lower end of inner bore 231 is preferably open, as shown, to allow the neck of the bottle to pass within cylindrical member 225 to engage the threads. The upper portion of the cylindrical member is preferably is capped by the upper stepped portion of base wall 216, as shown.

Transport-tube coupler 234 preferably comprises a hollow cylindrical extension of liquid transport channel 232, as shown. Dip tube 205 is preferably engaged on transport-tube coupler 234 by sliding the inner bore of dip tube 205 over the outer circumferential surface of the coupler, as shown.

Dip tube 205 preferably functions to transport irrigation liquid 117 from the bottom interior portion of manually-deformable internal reservoir 107 upwardly to liquid transport channel 232. When assembled, volumetric reductions of the manually-deformable internal reservoir 107, by manual deformation of outer wall 126, assists injection of irrigation liquid 117 from nozzle portion 213. Upon reading the teachings of this specification, those skilled in the art will now appreciate that, under appropriate circumstances, considering such issues as design preference, user preferences, medical needs, marketing preferences, cost, structural requirements, available materials, technological advances, etc., other discharge methods, such as, for example, manual or electrical pumping, etc., may suffice.

The above-described structures of nasal irrigator 203 are preferably connectively unified into a single monolithic body, as shown.

In ordinary use, a user 114 preferably gently inserts bulb 214 of nozzle portion 213 within one nostril 209 while simultaneously placing the open end of effluent collector 204 below the open nostril 209, as generally illustrated in FIG. 11. With bulb 214 forming a liquid seal with the nostril 209, user 114 preferably gently squeezes irrigation squeeze bottle 102 to initiate the flow of irrigation liquid 117. Squeezing irrigation squeeze bottle 102 preferably deforms the outer wall 126 of irrigation squeeze bottle 102 so as to reduce the internal volume of the manually-deformable internal reservoir 107. Deforming outer wall 126 increases the pressure on irrigation liquid 117 contained within the manually-deformable internal reservoir 107, thus forcing the irrigation liquid 117 into tube inlet 206, through dip tube 205, and out discharge port 210 into the user's nasal passage and sinus cavity.

Liquid-containing effluent 118 draining from the opposing nostril 209 is preferably captured by effluent collector 204 which also acts as splash shield to prevent the effluent from splashing beyond the surrounding wall 218, as shown. In some preferred embodiments of the system, effluent collector 204 is preferably transparent so as to permit a physician to examine of the collected liquid-containing effluent 118 before being discarded.

Nozzle portion 313 preferably functions to facilitate the injection of irrigation liquid 117 into one or more otorhinologic structures of the patient's head (at least embodying herein at least one liquid injector structured and arranged to assist injection of the liquid into an otorhinologic structure of the head). In the present alternate embodiment, nozzle portion 313 preferably functions to administer a sterile liquid saline solution into the patient's nasal passages and sinus cavity. The preferred shape configuration of nozzle portion 313 is preferably that of a rounded bulb 314 with a frustoconical base. Nozzle portion 313 is preferably configured to form a seal with the patient's nostril 209 during treatment (see the similar illustration of FIG. 11). Thus, nasal bulb 314 preferably functions as an anatomical adapter to adapt the liquid-injecting structures of the apparatus to the anatomical geometries of the target otorhinologic structures of the patient's head.

The apparatus is preferably configured such that irrigation liquid 117 exits the distal end of nozzle portion 313 through a discharge port 310. When alternate nasal irrigator 303 is coupled with irrigation squeeze bottle 102, discharge port 310 is preferably in fluid communication with the manually-deformable internal reservoir within irrigation squeeze bottle 102.

The preferred symmetrical nozzle placement within effluent collector 304 preferably allows the open cup-shaped member 324 to be situated closely adjacent the face of the user. Preferably, the elevated surrounding wall 318 generates a splash shield 327 to assist in preventing splashing of liquid-containing effluent beyond the confines of the effluent collector.

Referring to the sectional view of FIG. 20 and FIG. 21, alternate nasal irrigator 303 preferably comprises one or more physical structures enabling the removable coupling of the apparatus to the irrigation squeeze bottle 102 shown in FIG. 19. In a preferred arrangement, threaded coupler 320 is preferably configured to threadably engage the external helical threads 122 formed within the cylindrical neck 103 of irrigation squeeze bottle 102 is formed within the base of effluent collector 304. As in the prior embodiments, a preferred coupler configuration comprises a cylindrical member 325, as shown.

As in the prior embodiments, the internal helical threads 323 of coupler 320 are preferably formed with a size and pitch providing near “universal” thread compatibility with the external helical threads 122 of irrigation bottles in the previously-noted range. Thus, coupler 320 is preferably designed to fit wide mouth standard irrigation bottles comprising slightly differing bottle end opening configurations.

With specific reference to FIGS. 38A-40F, further embodiments of the invention provide a nasal adapter without an effluent collector, which can accommodate at least one, and preferably more than one of a variety of different medical irrigation devices for administration of liquid into a patient's nostril.

Preferably, such nasal adapter without an effluent collector is configured to accommodate at least one, preferably at least more than one of a squirt bottle and syringe. More preferably, such nasal adapter is configured to accommodate at least one, preferably at least more than one of a squirt bottle, a syringe with Luer-Lock connector, and a syringe with Luer-slip-type connector.

Preferably, such nasal adapter is used to administer solution, preferably a sterile liquid saline solution preferably into the patient's nasal passages and sinus cavity for a preferred high flow, low pressure and low volume irrigation.

Preferably, a solution is administered by coupling the connector end of the nasal adapter to the medical irrigation devise, with the medical irrigation devise being at least partially filled with the irrigation liquid, and irrigating the nasal passage by bringing the nasal bulb portion of the nasal adapter into proximity with the nasal passage of the patient, then discharging the irrigation liquid into the nasal passage via a discharging mechanism (e.g. squeezing of the squirt bottle, or pumping of the syringe).

In use, the bulb portion of the nasal adapter assembled with a liquid containing device (e.g. syringe, squirt bottle) is pressed against the patients nostril, and the solution is administered by causing the liquid to be ejected from the device (e.g plunging, squeezing, etc. of the device).

Upon reading the teachings of this specification, those of ordinary skill in the art will understand that, under appropriate circumstances, considering such issues as design preference, user preferences, medical needs, marketing preferences, cost, structural requirements, available materials, technological advances, etc., such nasal adapter without an effluent collector may be configured to accommodate an attachable collector which may or may not include a splash shield (e.g. effluent collector 501 which is attachable between the device and nasal adapter).

Additionally, it is particularly advantageous to provide nasal adapters compatible with both standard wide mouth irrigation pour bottles available in hospitals and standard Luer lock syringes which are widespread in hospitals for use by trained medical personnel, to also be used for nasal irrigation.

Additionally, an adapter for standard wide mouth irrigation pour bottles, which are widespread in hospitals and clinics, can be particularly advantageous as it enables such bottle to be easily used for nasal irrigation. Such bottles typically contain medical grade irrigation fluid and may include features that maintain the sterility of the bottle. Additionally, it may be particularly advantageous to enable an at-home patient to use such bottle provided with sterile solution, as it may reduce potential risk of infection resulting from household water sources which the patient may need to otherwise mix with certain solutions. Thus, a reliable sterile saline source that is readily available and could be used with the disclosed nasal adapter may reduce infection risks for such patients that require irrigations, and is further advantageous for hospital patients with increased susceptibility to invading organisms.

Discharge port 903 preferably comprises a diameter of about ½ mm, preferably a diameter greater than ½ mm. Applicant has found it critical for discharge port 903 to have a larger diameter in order to flood and/or flush nasal passages; smaller diameters cause misting instead of flooding. Upon reading the teachings of this specification, those skilled in the art will now appreciate that, under appropriate circumstances, considering such issues as cost, available materials, etc., other discharge ports, such as, for example, multiple ports, multiple smaller ports discharging similar volumes, etc., may suffice. Upon reading the teachings of this specification, those of ordinary skill in the art will now understand that, under appropriate circumstances, considering such issues as leakage prevention, dip tube and syringe design, a nasal adapter configured to connect with a dip tube, as well as syringes with either a Luer-slip or Luer-lock, may suffice.

FIG. 39B shows adapter 900 connected to squeeze bottle 102 with the interior connector 904 of adapter 900 fitted with dip tube 205.

As will be understood by one skilled in the art, the above described adapter may be specifically designed to provide certain advantageous depending on the desired use and specific needs. For example, the nasal adapter of the present invention is preferably structured and arranged to accommodate large syringes with volumes preferably greater than 15 ml, preferably with prefilled sterile saline and a distal nasal adapter that could be used in some cases for large volume irrigation for example the nasal passages of an adult.

In another example, the described nasal adapter may be structured and arranged to specifically accommodate small volume prefilled preferably saline flush syringes, e.g. preferably around 5 ml, or 10 ml, for use with smaller pediatric or neonatal patients. This is particularly advantageous as larger volume bottle irrigation can be inappropriate for small children due to the inability to control the volume, including the limiting the volume. Additionally, such adapter can be designed to have a wide body for preventing risk associated with the adapter accidentally falling into a child's mouth.

Additionally, according to certain embodiments, the nasal adapter may be specifically structured to be easily attached and difficult to accidently remove. In some cases it would be desirable to have a syringe with a commonly used adapter, such as a Luer and Luer lock adapters, since the syringes would be readily available in medical facilities by trained personnel. Luer lock adapters are particularly useful due to their ability to retain an attached adapter from pulling forces. In other cases it might be useful to have non-Luer tipped syringes to avoid any connector misconnects or incompatibility to avoid medical errors, such as when oral syringes have been used for oral medication administration.
